National Tap Dance Day falls on May 25 every year and is a celebration of tap dancing as an American art form. The idea of National Tap Dance Day was first presented to U.S. Congress on February 7, 1989 and was signed into American law by President George H.W. Bush on November 8, 2004.[1] The one-time official observance was on May 25, 1989.[2][3] Tap Dance Day is also celebrated in other countries, particularly Japan, Australia, India and Iceland.

National Tap Dance Day was the brainchild of Carol Vaughn, Nicola Daval, and Linda Christensen. They deemed May 25 appropriate for this holiday because it is the birthday of Bill "Bojangles" Robinson, a significant contributor to tap dance.

Tap dance day can be celebrated with an event which may be organized by a studio or tap dance interest group. Some may also celebrate it individually due to geographical dispersion or lack of access to the wider tap community. National Tap Dance Day is celebrated in many different ways. For example, a studio may send people out onto the streets to teach the "Shim Sham Shimmy" to passers-by. However, there are several cities (particularly in America) that have their own performances and events to coincide with Tap Dance Day.
